    2 seconds to black. Take it apart and test the transformers, I'm not sure this TV used many transformers or just two on each side, but some Philips do.

      Are you referring to the transformers on the Inverters or the Power Supply?

            Looks like a Sharp panel, never seen one of those before in a Philips TV.

            Anyway you have a multi transformer inverter so test the secondary of all the transformers. If you need help locating the secondary post a closer shot of the inverter and one transformer.

              Samsung UN55H8000 sound but no backlight no video
              by Max514
              Hi all,

              Ok so I have this beautiful un55h8000 samsung tv with sound but no video nor backlight. When turning the set on the red light blinks 5 times.

              The screen shows no damage and backlight turns on when I disconnect the power supply from the main board. The tcon board only has 2 out of 3 leds on.

              I came across this page and followed the different steps: https://techhometravel.com/samsung-u...ight-no-video/
              • Unplugging the main board cable at the power supply >>> backlights came on.

              Vizio D32f-E1 Powers on, has backlight, won't boot/no logo, no menu or video
              by JaquesPratt
              I have a Vizio D32f-E1 LCD TV that does NOT have a TCON board.

              This TV recently went through some 'death throes' and now won't boot. The first problem that began to manifest was while watching tv, the screen would 'freeze', and the image would dim over a few seconds until it was very dark. HOWEVER, the audio of the show would continue as normal. I could power off the TV for 5-20 seconds, power back on, and the video would be normal. This would occur 1-3 times when the TV was first started, and would not happen again after the TV was 'warmed up'. Not ideal, but this glitch was manageable....

              UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
              by triplefour
              this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
              i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
              unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
              according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

              LG 43UK6300PLB has backlight but no video
              by edugimeno
              Hi! This TV was ready for the trash so I picked it up before it was thrown away

              It's pretty new, so I thought I should give it a try. I plugged it in at home and I was expecting blown backlight as most of the TV's that get to me, but in this case it showed backlight with no video at all (no logo no menu no nothing).

              TV seems internally responsive, drives stdby led red when OFF, responds to remote to turn on and off, but gets no image at all
              Anything common on these sets to start with?

              Thanks!...
